GEAR FOR PLAT'FORM-WAGONS'.

SPECIFICATION forming part of Letters Patent No. 282,455, dated July 31, 1883.

Application filed June 12, 1883. (No model.)

v To all whom it may concern.-

the. several parts. s

Be it known that I, MARTIN HALFPENNY, of Pontiac, county of Oakland, State of Michigan, have invented a new and useful Im'provement in Gears for Platform-Spring Wagons; and I declare the following to be a full, clear,

V and exact description of the same, such as will en able others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification. i My invention consists in the combinations of devices and appliances, hereinafter specified, and more particularly pointed out in the claims. r l In the drawings, Figure 1 is a side elevation of a device embodying my invention. Fig. 2 is a rear elevation of the same. Fig. 3 is a front elevation. Fig. 4.- is a plan View. Fig. 5 is aseparate view ot'the ball-and-socket joint; Fig. 6 is a separate view of the construction and location of the eyebolt. Fig. 7 is a separate View of the attachment ofthe end of the side spring.

My invention relates to gears for platformspring wagons, and has for its object an improved construction of the oscillating bolsters, the trusses, and the general arrangement of I11 carrying out my invention A is the front bolster, and A is the rear bolster, united by suitable braces, a.

Bis the circle, united to the front bolster by means of a clip, I), having a hinged or pivoted connection with the front bolster, as shown "at b, said bolster provided with aplate, a, secured thereto, by means of which this hinged or pivoted connection is accomplished.

O is a cross-.barconnecting the ends of the circle, and connected with the rear bolster by means of a ball-and-socket joint, as shown at 0. For this purpose the crossbar is-provided with a suitable plate, 0 the rear bolster being also provided with a plate, A, to correspond therewith, the two plates being connected by a king-bolt,. A having arounded "head, a

D and D represent the hounds, secured at their forward ends to a metallic head-plate, E, by means of suitable rivets or bolts, (1 and d, the ends of the hounds being preferably therein by means of a nut, 70.

a constructed angular in form, as shown in the drawings, for this purpose.

F and F represent supports riveted or bolted to, the hounds and to the circle. G represents the steps, preferably constructed with an angle plate or arm, G, riveted or boltedto the rear end. of the hounds, and prowith a flange, h, extending over the end of the hounds, the same rivets or bolts h securing both of said plates to the hounds.

'I and I represent rear braces secured at one extremity to the cross-bar G, and at the other extremity secured by a bolt, H, said bolt'passing through the plates H and G, as shown; said bolt also serving to hold said plates more firmly together. By means of the same bolt H the side spring, J is secured to the rear end of the gear.

K and K represent truss-rods extending longitudinally with the hounds. These rods are headed at their forward ends and passed through suitable shoulders, 6, upon the headplate E. At the rearends these truss-rods are passed through suitable orifices constructed in the flanges of the plates H and G, and secured of their ends these truss-rods are secured by means of an eyebolt, L,passing through a strut, N, said eyebolt passing through the crossbar O and the ends of the circle, and secured by a nut, l. The bolt L, passing through the strut M, extends upward upon one side ofthe hounds, as shown in Fig. 6. The strut M is also slotted, as shown at m, to receive the hounds.

N is a cross-truss secured beneath the crossbar 0, the ends of said truss being secured to the crossbar by means of the eyebolt L. Intermediate of its length the cross-truss isse- Intermediate cured to the cross-bar by means of a suitable supporting-bolt, n.

O is'a head-bloclrsecured in any suitable.

manner, preferably by bolts 0, beneath the headplate E,and towhich is attached the crossspring P.

Instead of making the step G integral with the plate or arm (9/, it is evident that the two may be separated, if desired.

I prefer to provide the plate 0 upon the cross-bar with upwardly-extending flanges c, to prevent the tilting of the bolsters too far,

' when they are oscillated from side to side, and

' (shown at b) permitting a perfectly-free os'cil lating and tilting movement. With this de vice the bolsters may be tilted as readily when the vehicle is cramped as when the line of moti on is straight forward.

What I claim is 1. I11 a platform-gearing, the combination, with the circle united at its ends by a crossbar,'of a front bolster, having a hinged or piv oted connection with a clip, adapted to travel upon said circle, and a rear bolster having. a ball-andsocket connection with said crossrbar, suitable hounds secured to a front head-plate, the circle, andthe crossbar, trusses extending longitudinally with said hounds, said trusses connected at their forward ends to said headplate, and at their rear by means of a nut to suitable connectingplates, H and G, secured upon the rear 'ends of the hounds, said trusses connected also, intermediate of their lengths, by means of a suitable bolt to'the crossbar, substantially as described. I

2. In a platform-gearing, the combination, with the hounds and front head-plate connected therewith, of longitudinal trusses secured to said head-plate, thence passing through an eyebolt extending-upward through struts M,

p slotted to receive said hounds, said trusses secured at their rear ends by means of nuts in connecting-plates secured upon said hounds, substantially as described.

3. The combination, in a platform-gearing, of a circle united at its ends by a cross-bar, hounds secured by suitable supports to the circle and by struts to the cross-bar, a front head-plate uniting the forward ends of said hounds, longitudinal truss-rods secured in said head-plate, and by an eyebolt through said struts, said trusses also secured at their rear ends by means of a nut in the connectingplates H and G, braces uniting the cross-bar with the hounds, and a cross-truss beneath the cross-bar, suitably connected therewith',sub-

stantially as described.

' 4. In a platforn1-gearing, the combination, with a circle united at its ends by a cross-bar, of a front bolster having a hinged or pivoted connection, with a clip adapted to travel upon the circle, a rear bolster having a ball-andsocketconnection with the cross-bar, hounds securedin avfront head-plate and rear con- 'necting-plates, trusses extending longitudinally with said hounds connected with said head-plate and rear connecting-plates, a crosstruss located beneath the cross-bar, and, in addition thereto, struts M, provided with suitable bolts, connecting the longitudinal trusses, the hounds, the cross-truss, and the ends of the circle to the cross-bar, substantially as described.

5. In a platform gearing, the combination, with the circle united at its ends by a crossbar, of bounds secured to a front head-plate, to the circle, and cross-bar, said hounds pro- Vided at their rear ends with connecting-plates H and G, trusses longitudinalwith the hounds,

secured at their forward ends in said headwith a clip adapted to travel upon the circle,

a rear bolster having a ball-and-socket connection with the cross-bar, hounds secured by suitable supports to the 'circle, and by struts M to the cross-bar, a front head-plate uniting the forward ends of said hounds, longitudinal truss-rods secured in said head-plate, and by an eyebolt to the cross-bar, said trusses also IOO secured at their rear ends, by means of a nut,

in connecting-plates H and G upon the rear endsof the hounds, braces uniting the crossbar with the hounds, a cross-truss beneath the cross-bar, and, in combination therewith, a head-block secured to the head-plate, across spring .secured to said head-block, and side springs connected with said cross-spring with the rear ends of the hounds, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

MARTIN HALFPENNY.
